We used the lab in the Orange Grove plaza. We had booked it in late December right after Canada make it a requirement to return, test was done on Friday and printed negative results were available for pickup Saturday which was our departure day. We payed $70 each at time of testing. PCR test is required for Canada so the Simpson Bay resort option was no good for us. We had several American friends use that facility and while the first night was a bit chaotic they improved things quickly. Getting tested in SXM was easier, cheaper and more efficient than in Canada. Things have gotten tighter in Canada now with testing before departure, testing on arrival and probably the deal breaker for most will be the mandatory quarantine at a hotel until your test are recieved (stated cost $2000 per person) if negative you must still quarantine at home for the rest of your 14 days. Our timing was fortunate as we were able to quarantine at home which we are now doing. The month in SXM was well worth the efforts.
